Any indications where yours was finally assembled ?

I don't see any wax paper caps here. Are they all micas, discs and ceramics?

Quite impressive craftsmanship. It has the feel of a Dumont set made close to mil spec, with pre-war looking parts.

That's exactly what I thought.

Rather obvious from the family photos that filthy, Godless Commies & Murricans were/are more alike than 1st imagined. That family pic could have easily been Americans-I've seen dozens thru the years. The Americans qould have likely been wearing big hats & holding rifles, though. Always suspected Russians & Americans would have generally been fast friends if the language barrier could have been overcome, & our 2 idiot governments had been gotten outta the way...

Totally agree!



The reverse example for me. Apart from the background, I could decide that there're some normal Russian builders from the 1930s having their lunch

We are pretty similar by nature, physically and even mentally, and our nations have a lot to share! Let's be friends, do deals, share experiences, and leave the politicians to play their own games!

Back to the CRT. I should explain why I'm so eager about rebuilding. I have a number of exhausted picture tubes on hands, beside the one intended to vts1134. Visiting the rebuild shop requires two pretty long drives (about 150 miles each way), to bring the tubes there and back, accordingly. Thus I move and move my rebuilding plans, waiting for John's decision and wondering how soon the shop may go out of business...

Sorry for not replying Gleb. I have been extremely busy and my TV collecting has taken a back seat currently. I've replied to your email.

Nothing changes, still not replying. I'm gonna make a rebuilding trip in early March, whether or not I take your picture tube.

Here is another video of a performing Leningrad-T2:

A fellow collector has just finished electronic restoration of his Russian-assembled set from 1949.

I believe he uses a modulator feeding it a composite signal.

Thanks, but I'm still wondering what kind of composite signal.

I was looking over the schematic when I noticed that it has only 2 stages of video IF but 3 stages of audio IF. Is that due to using the TV sound section for the FM radio?

With only 2 video IF stages, I don't think this TV Was intended for fringe areas.

[Gleb]

Most likely, the idea was in the use of either single or "overcoupled" IF coils / transformers, along with the high-gain 2 stage video amplifier. As a Leningrad's owner, I can't say that the TV's sensitivity is noticeably worse than others of the time, at least the ones with integral tuners. Later models with separate turret-style tuners do some better, of course.

I have 3(three) of the T-2 Leningrad and a few differnt russian roundies.
My experience is that the round CRTs, made in Easr Germany are mostly weak!

I am standing not alone with that!

You can easyly see on the speaker cloth the country of origin, East Germany
or Russia.

Do you need schematics for T-2 Leningrad?

I shouldn`t invest in another bad east-german made tube! The original 23 cm
CRT can easyly interchanged by a 22 cm Philips (MW 22 - __)

Source for that is good old England! PYE used them in the very familiar 1949/50
TV sets. The tubes are made by Philips and are mostly good.
See: http://www.tvhistory.tv/1950-59-PYE.htm

If you do that, you insert a tetrode by a triode CRT!

If you want to use a ion trap tube you have to change the deflection yoke.

It is told (by czech repairmen), that russian picture tubes likes to implode, be careful.

The schematic and the gate in front of the tube is based on the german
E-1 pre-war TV set.
The russian horiz. line out tube is based (optical and technical) on a german
war time tube.

The radio inside was available as a table set, too.

Good luck!

I forget to say, that the original CRT. has no ion trap!
Keep this in mind!
